feat: Auto-healing entry_point_discovery with browser-first transport

- Rewrote entry_point_discovery with auto-healing scheme:
  1. Check dutchie_discovery_locations for existing platform_location_id
  2. Browser-based GraphQL with 5x network retries
  3. Mark as needs_investigation on hard failure
- Browser (Puppeteer) is now DEFAULT transport - curl only when explicit
- Added migration 091 for tracking columns:
  - last_store_discovery_at: When store_discovery updated record
  - last_payload_at: When last product payload was saved
- Updated CODEBASE_MAP.md with transport rules documentation

+## Transport Rules (CRITICAL)
+
+**Browser-based (Puppeteer) is the DEFAULT transport. curl is ONLY allowed when explicitly specified.**
+
+### Transport Selection
+| `task.method` | Transport Used | Notes |
+|---------------|----------------|-------|
+| `null` | Browser (Puppeteer) | DEFAULT - use this for most tasks |
+| `'http'` | Browser (Puppeteer) | Explicit browser request |
+| `'curl'` | curl-impersonate | ONLY when explicitly needed |
+
+### Why Browser-First?
+1. **Anti-detection**: Puppeteer with StealthPlugin evades bot detection
+2. **Session cookies**: Browser maintains session state automatically
+3. **Fingerprinting**: Real browser fingerprint (TLS, headers, etc.)
+4. **Age gates**: Browser can click through age verification
+
+### Entry Point Discovery Auto-Healing
+The `entry_point_discovery` handler uses a healing strategy:
+
+```
+1. FIRST: Check dutchie_discovery_locations for existing platform_location_id
+   - By linked dutchie_discovery_id
+   - By slug match in discovery data
+   → If found, NO network call needed
+
+2. SECOND: Browser-based GraphQL (Puppeteer)
+   - 5x retries for network/proxy failures
+   - On HTTP 403: rotate proxy and retry
+   - On HTTP 404 after 2 attempts: mark as 'removed'
+
+3. HARD FAILURE: After exhausting options → 'needs_investigation'
+```
+
+### DO NOT Use curl Unless:
+- Task explicitly has `method = 'curl'`
+- You're testing curl-impersonate binaries
+- The API explicitly requires curl fingerprinting
+
+### Files
+| File | Transport | Purpose |
